How do I connect the msfs variable for the flaps position? The local variable name is FLAP_POS and has a range of 0.263-99.691. I want to map this output to a servo. So far everything I have tried gives me the error "Error stopping test mode: Input string not in a correct format." Right now I have the preset code set to "(L:FLAP_POS, 1)".

  1. Please specify which vendor and aircraft this is for?
  2. The error message is from where?
#
  1. Where did you get that preset code? It does not comply with proper RPN syntax. Units of 1 is not valid

  1. The aircraft is a T6A by BlackBird Simulations. 2. The error message is from the Mobiflight Console. 3. I do not remember where I found it, but it has been working for my LEDs.
#

For my lamp test switch which turns on all the LEDs in the cockpit I used the code: "(L:LAMP_TEST, 1)". This has been working without issue.

sorry to say, but that code is not correct. Units of 1 is not a valid unit.

#

(L:LAMP_TEST,Bool) is probably the correct code, where the Lvar can take values of either 0 or 1.

#

A servo cannot be set with a boolean variable, unless you only intend it to be either at zero point or fully rotated.

#

Servos only work on an integer scale, with only integer values.

#

If you want to learn RPN, then I suggest you start with the RPN guide in the msfs sdk web page.

Okay, I changed it to: (L:FLAP_LEVER, Int). FLAP_LEVER is an int. It is working, but in one of the servo positions the servo humms and gets a bit warm. How do I determine what "Max Rotation" it needs to be to stop it from trying to over extend?

int isalso not a valid unit

#

use units of "number"

#

but FLAPS_LEVER is given by the aircraft or is it your own defined Lvar? If given by the aircraft you need to use the units as given by the aircraft.
